Title: Exhaust filter device of internal-combustion engine
Inventor: USHIMURA MASAHARU
IPC: F01N3/02
Filed: 1983-06-03
Abstract: PURPOSE:To lessen the back pressure and prolong the period of use till clogging by using the partition wall between No.1 and No.2 cells as a filter, and by blocking the end of No.1 cell on its upper stream side with a draughty blocking material. CONSTITUTION:Exhaust gas containing fine particles mostly flows in No.1 cell 12a to be then exhausted through a partition wall 14 out to the atmosphere after being purified. The residual exhaust gas passes through a draughty blocking material 13b to get rid of fine particles to a certain extent, and then is released to the atmosphere. In the course of service, the caught particles are accumulated on the surface of said partition wall 14 to increase the resistance against air passage. Compared with any conventional construction, however, the passage area for exhaust gas has increased by a portion of draughtiness of this blocking material 13b used, so that the rise of back pressure is small.

Filed: 1987-04-21
Abstract: PURPOSE:To use a coordinate input device without trouble of convenience for use in case of the use as a mouse as well as a track ball by providing the coordinate input device with a signal switching means. CONSTITUTION:When coordinate input device 1 is placed on a desk or the like and is used as the mouse or the device 1 is inverted around an axis A and is used as the track ball when a ball 5 is turned to output a coordinate signal, a cursor must be moved in opposite directions to the turning direction of the ball 5 with respect to the y-axis direction in case of the use as the mouse and the use as the track ball. Consequently, a changeover switch 4 is switched between the use of the coordinate input device 1 as the mouse and the use as the track ball. That is, though a sense of operation of a user and the actual moving direction do not coincide between rotation of the ball accompanied with movement of an enclosure and direct rotation of the ball with respect to a certain axis of the rectangular coordinate system on a display device, they coincide by switching of the changeover switch 4.
